IntroductionCellular respiration provides energy to all living organisms by collecting energy from food molecules. The cell then rearranges complex molecules to simpler molecules and uses that energy to make a molecule that stores energy called adenosine triphosphate also known as ATP. Cellular respiration can occur with or without oxygen. When it occurs without oxygen, it…

“Investigate the factors affecting the rate of yeast respiration” Lab Report Introduction The aim of this experiment was to investigate the effect of different amounts of a substrate on the respiration rate of yeast and to compare this to the effect of different amounts of glucose on the rate of yeast respiration. The substrate which…

Describe the role of the citric acid cycle as a central metabolic mechanism. Explain what happens to the cells’ abilities to oxidize acetyl CoA when intermediates of the cycle are drained off for amino acid biosynthesis. Glucose is a source of energy that is metabolized into glycolysis to pyruvate yielding ATP. To become more efficient,…

MicroevolutionMicroevolution is nothing but the small change that occurs in plants or animals because of genetic inconsistency present in the gene pool of the inhabitants. Microevolution could be the main cause for the origin of a new species. The changes  in allele (alternate terms of a gene) frequency, which could be a result of mutation,…

 Gene therapy is one of the promising fields of medicine which helps to treat and prevent incurable diseases. Some genetic diseases do not become manifest until well after birth, in some cases not until adulthood. In this case, gene therapy helps to identify and replace defective genes by healthy ones. Genes are specific sequences of…

Yeast is a singled celled fungus that contains protein and is part of the fermentation process. As explained in question nine, fermentation is the process of the breakdown of sugars by bacteria and yeast using a method of respiration without oxygen (anaerobic respiration). It involves a culture of yeast and a solution of sugar, producing…

Objectives: Observe the effects of cellular respiration on temperature in a closed system. Investigate carbon dioxide production in germinating pea seeds and crickets. Perform an investigative study of the rate of cellular respiration in both pea seeds and crickets at different temperatures. Compare the alcoholic fermentation of glucose, sucrose, and starch by yeast. Ultimately, the…

Background Research Yeast are eukaryotic microorganisms Just like other organisms, they must respire in order to survive. Respiration can be defined as the controlled release of energy from organic compounds to form adenosine troposphere (TAP). The type of respiration that occurs is called aerobic respiration. It occurs when glucose and oxygen are present. It can…

Exposing Development Development is a theory that scientist have extensive research on and hold many pieces of grounds to back up. Scientist have made many charts tabular arraies and images to seek and visualise the location of every species known to adult male. The current method of forming all of the known species is utilizing…

Genes are working parts of DNA and the biological units of heredity. Specific cistrons codification for specific traits that are found in a given being. For illustration, one cistron may code for oculus colour while another one may code for shoe size. Deoxyribonucleic acid is an highly complicated biological system. Many, if non most diseases…
